Combining two Internet connections may seem like rocket science, but it’s actually quite simple if you have the right channel bonding app like Speedify.
In this guide we’ll show you how you can use your Starlink satellite Internet via Wi-Fi together with a 4G / 5G cellular connection and then use Speedify to combine them.
Speedify bonds your Starlink with another Starlink, 4G/5G cellular, cable, DSL and splits traffic across them. If Starlink drops mid-call or mid-transfer, Speedify fails over to your remaining connections instantly.
NOTE: For best results, use internet connections from different sources. Joining one router over both Ethernet and Wi-Fi won't help.
Most Starlink users already run a second connection.
From a sample of 6,228 Starlink users on Speedify, 71% ran at least one other internet connection while using Starlink. Cellular is the most common choice of backup connection.

3 Steps to Combine Starlink and Cellular on a PC Using Speedify
Step 1: Connect to Your Starlink Wi-Fi Hotspot
First - make sure you setup your Starlink according to the instructions you received in the package. This includes setting up your new Starlink Wi-Fi network, along with your password.
Verify that your Wi-Fi is enabled on your PC and connected to a network.
Click on the Wi-Fi symbol in the lower right corner of the taskbar (systray). If you’re not already connected to a Wi-Fi hotspot, turn on Wi-Fi by clicking on the tile in the lower left side of the pop-up menu then select the Wi-Fi hotspot associated with your Starlink connection and enter the password to connect.
Step 2: Connect Your USB Cellular Adapter to Your PC
Connect your Cellular Adapter to a USB port on your PC. Some Cellular adapters require the use of proprietary dialer software to connect to the Internet. Be sure to follow the manufacturer's installation and operating instructions closely.
In order to verify that your cellular connection is active, click on the computer / Wi-Fi icon in the lower right area of the taskbar (systray) and check to see if a “Cellular” tile shows up.
Step 3: Download and Install Speedify
Last but certainly not least, download and install Speedify. Once running, Speedify will automatically detect your Starlink connection and any other available Internet connections and combine them for increased speed, security, and stability.
Need to keep several devices connected in areas with limited or spotty network coverage, like event venues, remote locations or when traveling? Get consistent and uninterrupted online activity for all your devices using Speedify's Pair & Share functionality, which allows you to share cellular data between multiple devices wirelessly.
By pairing devices, you can effectively distribute your cellular connection across them, improving overall performance, especially when other network options like Wi-Fi may be slow or unstable.
You can manage settings, view statistics, and even apply limits to individual connections by either clicking/tapping on them from the Dashboard or by navigating to the desired connection through the main Settings menu.
Speedify will work quietly in the background to optimize performance including prioritizing streaming web traffic to avoid stuttering, buffering and disconnects.
When using Starlink Internet, Speedify is the only VPN that makes your online experiences faster, more reliable, and more secure.
